There are no black and white truths on this issue. Some digitally mastered LPs sound very good; some sound nearly as bad as early CDs. The earlier the digital mastering the greater the risk of bad sound. No surprise there. Mastering engineers found ways to work around the digital limitations.
A couple months ago my local college jazz radio station got rid of all their LPs since they hadn't been played for a number of years. I visted the station and walked away with a large box of jazz LPs mostly from the 1985 to 1988 time period. I suspect the station got them as freebies when record labels were trying to promote FM playing time. The records are almost all in pristine condition and nearly all of them were digitally mastered. SOME of them have excellent sound quality but most of the major label records have some pretty obvious digital colorations.
