Unity 360 Video Player Issue

I have used Unity as development platform for playing 360 video in Samsung Oculus VR Application and everything was fine in terms of playing Top-Down or Side-by-Side issue. Recently, I have come across a strange issue while using Unity 360 Video Player on Samsung Oculus VR.

When object is nearer to lens video is blurred however when object is away from lens video is not blurred and plays very smoothly,

Can anybody explain the issue and can share the solution.
