Yes, the name was changed.

Now, if you change in the code preview the "viewport" (second drop-down list
on the left) from [Current Paragraph] to [Complete Source] or [Preamble
only], you will be able to see the LyX-written LaTeX preamble.
With Document>Settings>Fonts as
Roman: Palatino
SansDefault
TT Default
Math: Automatic
I get the preamble:
\documentclass[english]{article}
\usepackage{mathpazo}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage{babel}
i.e. there is no need for
> \usepackage{mathpazo}
in the custom LaTeX preamble (Document>Settings>LaTeX Preamble).

Now found the difference: You put \lambda in \mathrm.
Unfortunately, support for upright Greek letters in mathematics is
limited in traditional TeX. Standard TeX and most mathematical packages
use either italic Greek characters or a text font without Greek letters
with \mathrm. This is why you get an italic lambda with LatinModern or
Times but a wrong (text) character with Palatino.
For background and details, see
http://mirrors.ctan.org/macros/latex/contrib/isomath/isomath.html#oml-font-encoding
Do you really want an *upright* Lambda? This would indicate a
constant value or a physical unit (see, e.g.
http://old.iupac.org/standing/idcns/italic-roman_dec99.pdf).
If you put only the "max" and the unit into \mathrm, everything should be
fine (except for the missing space between value and unit).
Otherwise, see
http://mirrors.ctan.org/macros/latex/contrib/isomath/isomath.html#how-to-get-upright-small-greek-letters
for options to get upright Greek in 8-bit LaTeX maths or use non-TeX fonts
with Xe/LuaTeX.

just changed the fonts in settings from
palatino
helvetica
computer modern typewriter
to computer modern, which displaces the \lambda correctly.
But I don't like the font too much. Any alternatives?
It works here LyX 2.2.2, Debian/TeXlive17, Palatino
Can you test with View>Source whether the "mathpazo" package is used?
Thanks for your help.
I could, however, not find View>source, to check for mathpazo
I am using Lyx2.3.0 Debian/TeXlive2017
perhaps this is what you ment:
Code-preview pane
it showed
$\mathrm{\lambda_{max}=528nm}$
I have added in document>settings
\usepackage{mathpazo}
but that did not help either.
Wolfgang
You can also try with setting Fonts>Mathematics: Times Roman New TX
I tried this, but \lambda is not shown

Many: see

For palatino, I recommend newtxmath.
