No, and most likely never.
3K and 4K can't load CFW due to METLDR checks and proper encryption as well as a minimum installable FW. The only choice is ODE, which even now is blocked on 4.60.
There's no reason for any scene to do so, seeing as the PS3 is in its twilight and with no way to break chain of trust, there's no way to load any CFW. It hasn't changed in years.
Edit: Cobra's ODE will work for 4k slims. If you don't mind having a swap disc to boot your swap disc to boot your ISO (imo more trouble than it's worth)
