DVD vs Tubi/Pluto Quality

Hey y'all, got a question that I haven't been able to find an answer to online: how does the DVD quality compare to the streaming quality on Tubi/Pluto of the older Sentai series?

I've poked my head into a few of the shows and they're definitely not the highest quality bitrate (separate from their film quality). My local library has a ton of Sentai box sets, so I've been wondering if the physical releases are a higher quality way to watch those shows?

Thanks!
