I just bought a Sony KDL 40R45A 40" for my bedroom It is made by Foxcoon and has a Samsung panel (neither are necessarily bad things)
Hisense makes all of the Best buy Dynex/Insignia sets now since maybe 2010 ? (that would likley account for the improvement in those sets )I read that possibly TCL makes some Samsung sets could be Hisense also lots of brands use multiple suppliers . http://www.digitimes.com/news/a20131213PD200.html
How big of a screen was your old set vs your new set ? Bigger screens often look worse with HD Lite.( CATV and SAT) are severely compressed and to a lesser degree so is OTA . CATV and SAT are usually referred to HD Lite . Of the 5 sets here at least the Plasma and one smaller 32" screen here seem to handle it the best.
Ofc a pro ISF calibration is usually best or you can always DIY with the free AVS HD .709
files here at AVS or a Disney wow disc or something like that .I use the free downloadable AVS HD .709 files here at AVS.
Some sets (most) will not have sufficient brightness when set to ref. black, in that case I bring it up to or just slightly above the point it is not crushing black detail in a program . In any event these settings are at the least a very good starting point you can always set to preference for your room from there . I would not recommend going into the service menu unless you have sufficient tech. knowledge or experience you can brick a set in there
if not carefull.
HD Lite refers to the TV-program received by the viewer, which has been somehow compromised (reduced) in fidelity. In internet vernacular, HD-Lite generally refers to programming delivered by commercial (subscription-based) providers such as DirecTV, Dish Network, and the major cable-TV operators.
HD Lite can be achieved by any combination of several techniques. Rate-shaping dynamically adjusts allocated bit rate for each of a set of TV-channels, based on an allocation-policy (which can come from realtime video-analysis or an operator-specified program weighting.) Rate shaping allows a set of channels to be transmitted with less bandwidth, based on the statistical observation that not all channels display the same level of motion-activity at a given instant of time (or the period of observation.) Downsampling reduces the spatial (horizontal and/or vertical) resolution of the TV-program, reducing the TV-signal's pixel-rate, and therefore its bandwidth requirements. Thus far, customers have reported down sampling on "1080i" signals only; 1920x1080i can be downsampled to 1440x1080i or 1280x1080i, with a corresponding reduction in transmission bandwidth. In contrast, over-the-air (ATSC) broadcasts of 1080i are fixed at 1920x1080. Temporal (frame-rate) reduction has not been attempted yet, as it unacceptably changes the character of motion video sequences. -wikipedia-

OTA CATV OTA 1080i also has a reduced bit rate just not as bad as HD Lite . broadcast HDTV is compressed to transmit in a 6 Mhz (or less) bandwidth space .
Here is what ABC said about 1080i broadcast in 1989 when asked about the ATSC standards . Note they chose to broadcast 720P .

The 1080 x 1920 (1080I) interlace format specified in the ATSC standard CANNOT be compressed to fit in a 6MHz channel without creating objectionable artifacts and it has been recommended that the 1920 pixels be sub-sampled to 1440 to reduce compression artifacts. Therefore, encoder manufacturers have elected to discard approximately 25% of the picture for over-the-air transmission. -wikipedia- http://en.wikipedia.org/wiki/HD_Lite
