It's actually both, most smart phones have very tightly compact pixels, retina on iPhones etc. Its very readable. So much so the BBC guy on Twitter posted a screenshot of a perfectly readable ticker and said 'This isnt readable'.

This shouldn’t make a difference. Modern phone screens use scaling so it’s equivalent to a certain revolution (e.g. a modern iPhone will have a pixel resolution of 2x or 3x what it is actually rendering)

What i mean is, old phones, the physical screen may have meant the resolution was only 320 pixels wide. But with iPhones now, its actually double or treble that like you say, which benefits the ticker, not makes it unreadable.
