Of course home demo is the best. In the case of no home demo, I think you should consider two options. Option A is just keep the D400 because you will have nothing to lose or to regret for. Option B is to bite the bullet to upgrade to D440. I think people could still upgrade their Experts after Year 2016 though no one can enjoy discounted price on the upgrade then. Yours should have been bought before Year 2016 so you can not enjoy discounted price in upgrade anyway.
Frankly it is strange to trade D400 for a 220.
