@lalitk I have done with a few of them, such as Patricia Barber's A Fortnight in France as I believe we have discussed previously, some Japanese pressings, and some Linn hybrid layer's that aren't available on Qobuz, but for the albums that are on Qobuz, if there are any sq differences between the rips and streaming Qobuz I don't think it is worth the effort. I have 24 TB of storage capacity in my server, and I have used 140 GB of it. :)
But I haven't bought any downloads in many months either. Streaming Qobuz sounds so good, I am currently preferring to put my money into better components, cables, vibration control/coupling apparatus, then look at streaming filters/switches. I still haven't experimented with PGGB software, once I get around to that, maybe this winter when golf season is over and I get bored, then I might have plenty of upsampled remastered CD files in storage.
