The search algorithm isn't human, so regarding search result placement, all that matters is what the bots can detect. If the bots think those are collages, the bots will downgrade the listing visibility. There's no getting around how the bots are evaluating each listing other than to appease the bot gods. Of course, every seller is free to change listings or not, but the search bots will continue to evaluate listings according to what they see. Photo quality is a huge factor in how the listings are evaluated and the bots look at anything collage-esque as lower quality.
Shops with large and faithful followings, including healthy sales and good reviews, will be able to continue using whatever photos have been working all along. They will be able to somewhat override the impact of the "photo quality" factor in the search algorithm and continue to enjoy higher search result placement. Shops without such a history will see a drop in visibility unless they offer photos that meet the algorithm's quality standards.
