entre la B7 et la C7, c'était juste un pied différent, entre B8 et C8 la différence est à peine perceptible si configurée de la bonne manière
Dans les review la différence est quand même souvent notée comme marquée

The OLED55B8 (with its Alpha 7 chipset) falls short of the
OLED55C8(with its Alpha 9 chipset) in three key ways.
First and foremost, the B8 isn’t as bright. This seems odd, as you wouldn’t necessarily associate brightness with processing. But while the C8 measures around 800 nits on a 10% white HDR window, the B8 tops out at around 680 nits. That’s a not unsubstantial difference, and does make HDR pictures look less explosive and, well, HDR.
It also means there’s a touch less detail and toning information in the brightest parts of HDR pictures, and slightly less intensity in contrast-rich scenes. It can also lead to dark areas of shots sometimes looking slightly short of detail and overdominant.
The B8’s reduced processing power also means that it’s not as good at upscaling HD sources to 4K. The results look a little softer, and subtle colour blends are a little less astutely managed.
As I noted above, motion isn’t handled as well as it is on the C8 series either. There are distracting digital side effects and stutters if you use the Smooth or Clear settings respectively. A Motion Pro option uses black frame insertion to make motion look more filmic, but also makes the picture too dark.
The B8’s colours, meanwhile, aren’t quite as consistently balanced and natural-looking as they are on the C8s. And finally, the B8’s pictures are more prone to noise, especially in dark areas.
Let me reiterate, though, that while the C8 is unquestionably the better performer, the OLED55B8PLA remains a great performer for its money.
Surprisingly, the OLED55B8PLA manages to partner its stellar pict
