Answer is no - because in stores they use "store modes" which push blue in the image by 30+% and they display under halogen light, and they have light scatter from all the other TVs around, so you'll never see what you'd see at home.
Should you go with tests an buy what they recommend? Answer is also partly no - because at the high cost level weighing is largely subjective.
In the end it would be a mixture of both.
(Buy a LG OLED, or a TCL 55S517, or a Vizio P-Series F1 -- or a Sony 'that model' with zone based background brightening in flickering mode ("Backlight Master Drive™" should be the marketing word there - there should be a new one coming that was shown at CES.))
The next thing around the corner is "better motion resolution", which is actually dearly needed, but the jury is still out on how thats going (This years fall TVs).
Also you almost cant buy 1080p sets these days. Think of 4k as something you almost get 'for free' because it was important for everyone to have it because of a marketing race.

If you dont care about HDR, and dont care about the inkiest blacks, you could actually buy VERY low cost, and depending on panel characteristics (how good is the rec709 color mapping ("calibration")). Rec709 (non HDR Bluray stuff, 90% of the HD content out there) has matured and everyone can do it.
Then you would go into - is viewing angle important? And maybe buy a Samsung non-QLED.
But TCL and Vizio were aggressive with full array local dimming pricing on the two models listed, so you get better blacks at LCD prices with them. The question is, do you need it?
If you are way into HDR these days, you'd probably go with a SONY LCD or a Samsung QLED - but you shouldnt (see issues with HDR).
Everyone and their mother is recommending OLEDs for their "perfect black", which in fact, you might not need so much (full array local dimming black on LCDs is good enough). Also they have the best viewing angles currently, but suck at HDR comparatively to other high end TVs.

Also the next battle ground will be motion resolution, which is overdue - because, all TVs motion performance nowadays sucks.
(When the image moves fast, it smears on screen or in your eyes. Compared to Plasmas or CRTs of old)
How that pans out, well see at the end of the year.

Buy what the wirecutter tells you:
https://thewirecutter.com/guides/buying-a-tv/
Or an LG OLED. Or a Panasonic OLED (better color much higher price, no Dolby Vision (?)). Or a high priced SONY TV with "Backlight Master Drive™".
Dont buy Samsung in the high price segment yet (maybe they bring out better products in the end of the year).
If you dont care about best black level, best motion performance (which still suck) or HDR - buy anything, that has a decent review on color accuracy out of the box, and is cheap.
If you spend more money, make sure you get a 120Hz panel (or at least a 60Hz panel that can do 48hz for judderfree 24p (there arent usually many of them out there)). Oleds have 120Hz panels. Dont go with manufacturer Hz figueres, they fake them (480+Hz! (=we made up)).
And before you decide on which one - go into the store and check the haptics. How you like the remote, how you like the menues, and stuff.
Never buy a TV because of their SMART capabilities. Buy an Apple TV box (HDR10, DV best implemented (?)), or a Fire TV or a Roku afterwards.
Yes - its really that indiscernible and chaotic..
Which is also why everyone just says buy OLED - but thats really not the jinx of it. They are good - but they arent necessarily that good for the price (chinese manufacturer have cheap prices) - and 'what is best' depends on how you weigh certain aspects.
