Yes,
Get a Blu-ray Calibration disc.
I used and continue to use 'Digital Video Essentials'. Calibrate your TV to match the player. Bargain, only paid around £13 from Amazon. Have spend hundreds upgrading cables etc. over the years yet pointless if current kit isn't set up to perfection.
Also run my Panasonic DMP-BD80 via a Tacima Mains Conditioner (£30) which has improved both sound and picture.
