Not on my TV, it isn't. I have a QM7 and Dolby Vision looks much better for gaming than standard HDR10 does. I don't game on PC, so Xbox has games I wouldn't have access to otherwise. Then there's Game Pass, and since I can't find a reasonably priced physical copy of Expedition 33 on PS5, it's better to enjoy it on GP for the time being.
On PS3 I have around 100 physical games, on PS4 I have around 80 physical games, on PS5 I have around 15 physical games. I guess part of the reason is the generation itself is just disappointing to me compared to others.
Everyone is different, so don't stress out on what other people prefer. Just enjoy what you like.
