I assume that by "real print" you mean a print made in a traditional color darkroom. And as I understand it, you're asking whether a digital print from 8x10 color negative film will be superior to a print made from 4x5 color negative film in a traditional color darkroom. I don't know exactly what you have in mind with the word "superior" but to me it means not just detail but also things like better local contrast, color saturation, color balance, etc.
IMHO the answer is unequivocally "yes," but not so much because the digital print is from 8x10 film while the darkroom print is from 4x5 as because any normal size film that's scanned and printed digitally by someone using good equipment and who knows what they're doing will be superior to the same size film printed in a color darkroom unless perhaps the color darkroom worker is well versed in the intricacies of masking. I add that qualification only because I never became involved with masking when I had a color darkroom and so can't speak from experience.
But I've done a fair amount of color darkroom work with negative film and I've done plenty of digital work and to me there just is no comparison between the quality of the prints that can be made with the two methods. In a color darkroom without masking you can make two basic adjustments - exposure and color balance. Once you have those two things right you're pretty well finished. You can sometimes do a very minimal amount of dodging and burning but it's hard to do even that without messing up the color balance in the areas dodged and burned. With digital you can do those basic things very easily and much much more.
Those are of course just my opinions, others might differ, but they are based on extensive experience with 4x5 and 8x10 film and with darkroom and digital printing.
