There is some of that in the 5e core books at least. Like the drawings for the conditions.I like the 5e art, but I wished they also used black and white line art.
I started with 2e, so I think that the art styles of Elmore and Caldwell, et al, will always be my favourite.
However, I’d say 5e art is overall the best of WotC D&D art. As much as I dislike Dragon Heist as an adventure, I think it has some of the best art I’ve ever seen in D&D books. There’s some absolutely stunningly gorgeous art in there, particularly the two-page spreads of the urchins.
I also like that 5e art is better at portraying diverse cultures and (mostly) doesn’t portray women as pin-up eye candy for randy young men like Elmore and Caldwell always did. (Is that what people mean by “cheesecake”?)
