Over 3,000 products, unique SEO for all?

I sell across maybe 10 categories with some categories having close 500/600 products each. If I was to use an example, one category is physical prints. The print style, material, size and use is all the same the only difference would be the design on the print. The prints are categorised into sub categories/themes. At the moment each of these ‘products’ has the below: Differences • Titles are 50% the same, with the other 50% being unique to that product. • Images have unique alt tags to that design • Unique SEO page title Same content • Main description is the same across all pages • SEO page description is the same across all pages My question is, should each of these pages be entirely unique. Ie the main descriptions being different/worded different but focusing still on the keywords for my niche?
