Customs will not open the package if the packing slip is correct. The TV box will say what the packing slip will say. Plus Amazon.co.uk is not known to fool custom officers. I do not see issues with delivery from abroad to landing port. After all, all flat panels (the display) are imported in India and then manufactured here. Many high end TVs are directly imported.
The problem will be ground transport in India. Another issue is the Amazon.co.uk does not ship such items to India.
