ABC, like ChordPro, is a loosely defined format. Renderers have lots of freedom in how the result will look.
The way MobileSheets renders ChordPro is accurate, but there are slight (hopefully harmless) differences with the rendering of ChordPro and other tools. This will be the case for ABC as well. Smaller page width, different fonts, ...

When you process an ABC source with abcsvg you will get a different result than when you include the source in the ChordPro program. It also uses abcsvg but different page width, different fonts, ...

As soon as MobileSheets supports images in ChordPro I'll add an option to the ChordPro program to turn the ABC data into an SVG image so you'll get near identical results. But you'll lose the ability to transpose in MobileSheets.

Bottom line: Expect good results, but do not expect identical results.

On the other hand, when you give the same piece of music to different musicians, you'll get slightly different results as well ☺.
