Code blocks (code sandwiched between 3 backticks each) are distinguishable because they have the grey background and set a monospaced font.
However, inline code (between 1 backtick on either side) does not seem to set a grey background, which makes it difficult to distinguish, as the only difference then between normal text and inline code is the monospaced font being set. This problem becomes worse, then for users who use a monospaced font to begin with, as there is virtually no change.
Ideally, the grey background could be enabled for inline code in the same style as codeblocks.
Here is a screenshot to give an idea how it looks for users who have set a monospaced font.
