There's that, and the fact HDR came to PS4 only as an afterthought, it was actually up in the air whether CDPR were going to do it at all. Apparently it's fine on XB1. Also, their first HDR patch messed badly with the performance, and their fix for it actually resulted in improved HDR for the most part ... except for this:
They're not going to patch it. They've said no more patches are coming. And there's no option in game to turn off HDR. So when playing the game on PS4, you have to turn off HDR in the game's settings. CDPR don't care about the PS4, they're pnly making it on multiple consoles because of the sales.
Furthermore, given how advanced Cyberpunk is sounding, I'm expecting a marked differential between the XB1X and PS4 Pro versions of this game. I can't speak for the next gen of consoles because we have no idea on specs yet.
