It wouldn't make any difference.
All the Precision Landing feature doesn't need a landing pad.
All it requires is that the terrain features of the Home Point must be sufficiently distinctive.
It has to have a recognisable pattern or texture.
Terrain such as a snow-covered field is not suitable.

To elaborate, any visually uniform surface where it looks the same if shifted 5-10 feet will not work.
BUT! In my experience the PL feature is quite sensitive, as would be expected from the optical flow tech in VPS, so if you can see distinct features like asphalt cracks, etc., at 20ft through the camera, the drone will be able to see them too, and PL will work – although it's using the VPS cameras. One really good TO spot I use often is the end of a parking lot space line.
Re: GPS accuracy... While consumer grade GPS can be as bad as ±15m, that's very unusual. Our systems use averaging, and in my own experience usually is accurate to within a few feet (±1-2m) virtually every time I let RTH bring it back and land.
I've never had a GPS deviation under these circumstances as big as 20ft, mentioned elsewhere. I assume the typical accuracy in flight is similar to what I see on landing.
