I just completed some cabinet doors using red oak quartersawn veneer plywood as the field. I sanded them lightly with 150 grit sandpaper and finished them with light danish oil.
After applying the finish I noticed a regular stripe, perpendicular to the grain with a darker and slightly cloudy appearance. Not at all attractive.
Dissatisfied I took one door and carefully scraped the surface with a cabinet scraper. Unfortunately the cloudy stripes are still there.
Are these planner marks or marks left by the veneer slicer and is there any way to get rid of them? I’d scrape or snad further but am concerned I’ll thin the veneer to far.

The knives on veneer slicers do occasionally get nicked and leave small tell-tale hairline beads perpendicular to the grain. But what you describe sounds more likely to be a burn mark, or snipe, from a sanding drum on the thickness sander used to surface the plywood after it was laid up. You can try to sand it out by hand, but you do risk going through the veneer (which is probably less than 1/64" thick).
*Thanks Jed,Guess I'll have to live with it. Next time I'll pass on using plywood.
