The Apps can often be similar, depending on the model of TV and Blu-Ray player you have.
If you want to use the TV's SmartTV option only, you can launch only the TV's SmartTV interface with the TV's remote and not use the Blu-Ray's lineup. Since it's installed on both, there's not a way to "uninstall" the SmartTV features, but you can avoid it by not launching it.
If we can help further, please let us know how we can help.
Thanks for your support of Samsung products.
