Hello.
I have a question.
The following figure is the noise figure for the LTC6655 from the datasheet.
Do you have a diagram of LTC6655LN measured under the same conditions as this one?

The datasheet doesn't have a diagram for the LTC6655LN but it does provide output voltage noise specs in the electrical characteristics table.
The LTC6655-2.5 has a typical 0.1Hz to 10Hz output voltage noise of 0.25 ppmp-p (625nVp-p). This can be viewed in the diagram you've included.
The LTC6655LN-2.5 has a typical 0.1Hz to 10Hz output voltage noise of 0.12 ppmp-p (300nVp-p) when CNR = 100uF. This is approximately half of the peak-to-peak noise when compared to the LTC6655-2.5.
The core of both products is the same, the NR capacitor rolls off noise based on an internal impedance.
