Those are small changes but the good news is the new software will also be available for the 320 and 520.
This is only half true
The software update with the new "HDR contrast" control will also include HLG support and will indeed come to 520 and 320. Several "eye witnesses" at IFA have said that "HDR contrast" works really, really well and will make the Sony projectors have the best (and most "out of the box") HDR implementation yet.
Reality Creation has also been upgraded, but this is a hardware-based feature that the 520/320 will not get.
Also it is definitely confirmed that both HDMI inputs on the 550 are full 18 Gbps inputs.
Asked for a 4K FI, the Sony representatives said they're working on it, but for this generation of projectors it just wasn't possible b/o the hardware requirements.
Ekki (from Cine4Home) who did the presentation also showed the 550 in a mini shootout with the JVC X5000 (RS400). With UHD material, the Sony was significantly sharper and HDR looked better as well.
Interestingly, Ekki was also able to show how JVC "cheats" its way around the 4K FI problem. As we know, with UHD material the current JVCs do have a working FI; we didnt't know that they only use half the pixels of the original picture
This was demonstrated with three 4K fotos: 1. Woman, 2. Forrest, 3. Hybrid: 1st pixel from Woman, 2nd pixel from Forrest, 3rd pixel from Woman, 4th pixel from Forrest and so on. What did the e-shifting JVC show? 1. Woman, 2. Forrest, 3. Woman
The third picture was indeed identical to the first one, proving that the e-shift actually used only every 2nd pixel of the original 4K foto and hence all the "forrest pixels" from the hybrid foto were just gone!
