Will a mirror screen protector hide the cracks on my iPhone?

So two days ago I was playing outside and I was checking the time on my iPhone and it fell on the street so the top half of the phone cracked, it didn't effect the phone at all except its hard to see with all these cracks and scratches on it and plus it looks stupid. So my friend told me if I buy a mirror screen protector or a reflective screen protector it will hide all cracks and scratches on my phone. So I'm asking is this true and will it work really good?

Well itll hide the scratches but i'm not sure if itll cover cracks. I don't really like mirror screen protectors because it makes it hard to see outside and especially when the sun is out it makes it look rainbowish so you can't see the screen.

It depends on how severe the crack is and the position of the crack but chances are no, it won't hide it.
