Is Amazon Prime Video (digital) extended collection (6 films) 4K?

Hi,

Does anyone know if the Amazon Prime Extended Collection is 4K?

https://www.amazon.co.uk/gp/video/detail/B0D72JDG73/ref=atv_sr_fle_c_Tn74RA_1_1_1?sr=1-1&pageTypeIdSource=ASIN&pageTypeId=B0D729YR6L&qid=1763659257763

I bought them on YouTube a long time ago and they are no longer 4k, heck not even HD

So looking to repurchase, it's rewatch season..

Thanks
