No indication before purchase if it is 1080 or 2160p etc

Why is there no longer any indication before purchase that the video is in SD, 720p, 1080p, or 2160p as before? I have no intention of purchasing if I don't know what resolution are available

If the video is in 4K, you can find the tag on the preview.

Another method is checking the version of a trailer, they are usually the same as the full video.

but there is no indication if they're 1080p as it used to
