Turntable leveling


Pardon the possible obtuseness of the question, but - in the opinion of forum readers - how important to sound quality, LP and stylus wear is having my turntable precisely level? Try as I might, I can't get it <2 degrees from absolutely horizontal measuring with the Levlx iOS app though it looks good with a bubble gauge. I've looked online and I can't find a consensus opinion on this matter though I know the more level the better.
Thanks in advance,Keith

@cleeds Slight exaggeration for effect. I have dialed in tiny adjustments though. I have a 1962 Julie Andrews record which responds to the tiniest change which snaps the vocal into pinpoint focus.
Cross check level at Home Depot $3.96
VPI cross check level at Music Direct $10.00

The old level-level saga...easily determined by placing the level on a surface, noting the reading, rotating the level 180 degrees and placing it on the exact same spot and again noting the reading. If the readings are the same...the level is level.
+1 with Glen; level the platter surface and the tonearm mount board or achieve the same degree and direction of error for both. Forgot to bring that up.
My turntable sits on a 150 lb circular granite slab glued to a gimballed gearing from which hangs a 250 pound pendulum. It is accurate to 1/1000 of a degree. Just kidding. A spirit level is all you will ever need.
