Are movie and show file sizes more efficient than they were years ago? (lemm.ee)

This may be a stupid question, but I just got back into pirating some shows and movies and realize that many of the QxR files are much smaller than what I downloaded in the past. Is it likely that I am sacrificing a noticeable amount of quality if I replace my files with the smaller QxR ones?

For example, I have Spirited Away from 2017 at 9.83 GB, but I see the QxR is only 6.1 GB. I also have the office from 2019 and the entire show (no bonus content) is about 442 GB, while the QxR version is only 165.7 GB. Dates are what they are dated on my hard drive, can't speak to their actual origin, but they would've been from RARBG. (Edit to add: I also can't really speak to the quality of the downloads, back then I was just grabbing whatever was available at a reasonable size, so I wasn't deliberately seeking out high quality movies and shows - a simple 1080p in the listing was enough for me).

I did some side by side on episodes of the Office (on my PC with headphones, nothing substantial), and I don't notice any differences between the two.

Thoughts on this? Are people better at ripping/compressing/whatever now that they can do so at a smaller size without sacrificing noticeable quality?

op is describing the source video file bitrate, not the target codec bitrate. 6000kbps compresses to different amounts depending on the codec and quality used. Op doesnt mention the quality factor for the codecs, so this is less than helpful.

You choose the output bitrate by adjusting the quality. If you ask for a 3GB file you get a 3GB file.

Unless you switch to using crf, which tries to give a consistent quality level, damn the file size.

Of course there are different ways to select the quality level. CRF numbers don't mean anything though, they're just higher or lower than each other.
