Tolkien wrote an epic poem about Arthur (https://www.amazon.co.uk/Fall-Arthur-J-R-Tolkien/dp/0007557302/). Can it be that he disliked what some other authors did with the legend?

If you order it BRAND NEW from Blackwells, Waterstones etc it'll very likely be the SIGURD AND GUDRUN-esque style. Buying through Amazon UK (either Amazon (leftover stock_ themselves or another seller) or Abe MAY get you older black (and very yucky looking) one https://www.amazon.co.uk/Fall-Arthur-J-R-Tolkien/dp/0007557302/ref=sr_1_1?keywords=fall+of+arthur&qid=1630008465&s=books&sr=1-1 .

Please be aware: the two editions you linked in the last line of your post ("So:") do NOT match the rest in the series, in terms of height. Book Depository MAY have the black one up for the product page, as it's the same ISBN. There's been a few times (outside of Tolkien too) where if a cover design changes, yet the ISBN remains the same, the product image won't "catch up".
